Update utils unit tests

[kubark42]

All the unit test stuff is finally coming together. It runs the way it should now, and no longer trips across the range of utils_norm_angle().

Successful test output below:

vesc % make all_ut_run    
*NOTE*      Sanitized disallowed variable 'TMPDIR' from environment
*NOTE*     Parallel make disabled by all_ut_run target so we have sane console output
